High Speed Strike Weapon (HSSW)

The High Speed Strike Weapon (HSSW) is a hypersonic missile concept suitable for future bomber and fighter aircraft.

Lockheed Martin’s Skunk Works® is leveraging its proven experience in high Mach systems to provide an affordable, practical and compact solution. The HSSW will enable a responsive strike capability on time-critical, heavily defended targets and achieves high survivability through altitude, speed and stealth.

The HSSW will not only demonstrate hypersonic flight but also paves the way for future hypersonic programs, including both expendable missiles and reusable aircraft.
